• Every detail of the Jett Multispeed—including the 130mm Bridge saddle, narrower-diameter grips, and short-reach, tool-less adjustable brake levers—was informed by Retül data from a kids’ research group to be perfectly proportional for young riders.
• A lightweight bike is simply more fun and the Jett Multispeed’s all-new A1 aluminum frame, alloy fork, Pathfinder tires, and 7-speed drivetrain make it one of the lightest kids’ bikes on the market.
Occasionally, without notice, manufacturers change product design and/or specifications.
